Abstract
This work is within the scope of set of consultancy studies made for Portuguese islands. It focuses on the integration of Pumped Storage Power in isolated islands. The paper starts to address several power systems circumstances about two Portuguese islands on the energetic level. For each of these islands, an independent examination of the conditions to install a reversible hydro power plant is accomplished. Therefore, the energy volume to be stored due to excess of renewable generation and the ideal power and number of the pumps and turbines to be installed were identified and evaluated for the sake of using the produced energy surplus as to be pumped and later generated. The paper enhances the importance of storing energy in the operation of isolated and small systems with considerable amount of intermittent power resources as well as the conditions for the viability of installing new exploitations of this kind.

Abstract
Human language constantly evolves due to the changing world and the need for easier forms of expression and communication. Our knowledge of language evolution is however still fragmentary despite significant interest of both researchers as well as wider public in the evolution of language. In this paper, we present an interactive framework that permits users study the evolution of words and concepts. The system we propose offers a rich online interface allowing arbitrary queries and complex analytics over large scale historical textual data, letting users investigate changes in meaning, context and word relationships across time.

Abstract
Prosumers represent an important building block under the paradigm of a decentralized energy landscape such as outlined in the EU Clean Energy Package. However, the synergetic use of distributed resources such as electric vehicles (EV) or residential roof-integrated photovoltaics (PV) on household or neighbourhood level requires their diffusion patterns being temporally and spatially synchronized. This paper is dedicated to the joint analysis of their adoption patterns, using spatial analysis interfaced with mutual information and criteria ranking analysis. Surprisingly, outcomes for Portugal suggest that residential photovoltaics and electric vehicles are adopted by different population layers, as their occurrence is linked to diverging sets of sociodemographic criteria. Furthermore, an analysis of these criteria sets shows that their internal composition (the driving factors behind EV and PV adoption) varies among regions which has important implications on electricity network planning.

Abstract
In this paper, we studied 2017' indexes related to people life conditions: happiness, prosperity, sustainable mobility, quality of life. Some quality of life sub-indexes, regarding mobility, traffic commute time and the pollution, were also considered. A two variable representation was displayed through a simple regression, in order to measure the strength level of the relations between the variables and their influence towards the adoption of sustainable mobility practices. It was possible to conclude that the strongest correlations found were between the happiness and the prosperity indexes; the traffic commute time and the quality of life indexes, by cities; and the pollution and the quality of life indexes, by cities, which aim to explain sustainable mobility behaviors and its impact in the improvement of the population well-being and satisfaction. The information compiled in this study might be relevant to a large group of stakeholders and decision-makers, focused on the definition of policies to increase the citizens' quality of life. This study might be, also useful for increasing the degree of awareness and involvement of the population through the adoption of mobility solutions that will be critical to creating a sustainable way of life in the future.
